We tested deleting the template on primary storage, and it failed to regenerate.
What is the documented method for registering the new template, can you link to it? It seems many of us failed to find any documentation about updating the template period, not just in the 4.2 release doc under upgrades from 4.1 Thanks.

I figure one should be able to register the template, via the documented route... wait for download to succeed, upgrade the binary bits. then when the system vm's fail to launch. delete the cached template on primary storage. That should be enough to trigger a new system vm propagated to the primary storage. I find it hard to believe this passed QA...
